Abstract (en)
[origin: EP0681228A1] The coupling system (1) between the mechanical energy source (2) and an electrical generator (3) in a timepiece has a shaft (4), driven by the mechanical source (2), and a cylindrical element (5) coaxially fixed on this shaft (4). Over the cylinder (5) is mounted a tube (6) which freely turns on the shaft (4) and which is arranged to drive the generator (3). A helicoidal spring(7) is adjusted so as to rub against the tube (6) by means of its first (8) and last (9) turns. A space (10) is formed between the tube (6) and the cylindrical element (5) and the central turns (11) of the spring. <IMAGE>
